Kuti uwane kuzadzikiswa kwakazara kweiyo photovoltaic (PV) magetsi chirimwa, chingave chidiki, chakaiswa padenga reimba yemhuri kana hombe, ichiwedzera munzvimbo dzakakura, zvinodikanwa kugadzira chirongwa chakaomarara. Iyo purojekiti inosanganisira kusarudzika kwakaringana kwePV mapaneru uye zvimwe zvinhu senge michina dhizaini, optimum wiring system (yakakodzera nzvimbo yezvinhu, kugadzirisa kwakaringana kwekombiji, kubatana kwekudzivirira kana dziviriro yenetiweki) pamwe nekunze nekudzivirira kwemukati kurwisa mheni nekuwandisa. Iyo LSP Kambani inopa ekuwedzera ekuchengetedza michina (SPD), iyo inogona kuchengetedza yako investimenti pachikamu chidiki chemutengo wese wekutenga. Usati wajekesa zvigadzirwa zvekudzivirira zvekuwedzera, zvinodikanwa kuti uzive neakanyanya mapikicha e photovoltaic uye kubatana kwavo. Ruzivo urwu runopa data rekutanga kusarudzwa kweSPD. Izvo zvine chekuita nehurefu hwakavhurika-wedunhu voltage yeiyo PV pani kana tambo (cheni yemapaneli akabatanidzwa mune akateedzana). Kubatana kwePV mapaneru mune akateedzana kunowedzera iyo yakazara DC magetsi, ayo anozoshandurwa kuita AC voltage mune inverters. Zvikuru zvihombe zvinogona kusvika 1000 V DC. Vhura-wedunhu voltage yeiyo PV pani inotsanangurwa nekukwirisa kwemazuva ezuva anowira pamapaneru maseru uye tembiricha. Inokwira nemwaranzi iri kukura, asi inodonha nekukwira kwetembiricha.

Chimwe chinhu chakakosha chinosanganisira kuiswa kweyekunze mheni yekudzivirira system - tsvimbo yemheni. Iyo yakajairwa CSN EN 62305 ed. 2 pamusoro peKudzivirirwa pamheni, Chikamu 1 kusvika ku4 chinotsanangura marudzi ekurasikirwa, njodzi, masisitimu ekudzivirira mheni, mwero wekudzivirira mheni uye nhanho yakakwana yekukwirisa. Aya mana emagetsi ekudzivirira mazinga (I kusvika IV) anoona paramende yemheni mheni uye kutsunga kunopihwa nedanho renjodzi.

Mukutaura, pane mamiriro maviri. Muchiitiko chekutanga, kuchengetedzwa kwechinhu neyekunze mheni yekudzivirira system inodiwa, asi iyo arcing daro (kureva iyo nhambwe iri pakati peyemhepo-inogumisa network uye iyo PV system) haigone kuchengetedzwa. Pasi pemamiriro aya, zvakafanira kuti uone kubatana kwegalvanic pakati penzvimbo yekumisa mhepo netiweki yekutsigira yemapaneru ePV kana mafuremu ePV. Mheni dzinoyerera ini_imp (impulse yazvino ine paramende ye10 / 350 μs) anokwanisa kupinda mumatunhu eDDC; nokudaro zvinodikanwa kuisa mhando 1 yekudzivirira yekudzivirira chishandiso. LSP inopa mhinduro inokodzera muchimiro chakabatanidzwa 1 + 2 mhando yekudzivirira ekuchengetedza michina FLP7-PV akateedzana, ayo anogadzirirwa iwo magetsi e600 V, 800 V uye 1000 V aine kana asina kure kure chiratidzo. Muchiitiko chechipiri, hapana kudikanwa kwekushongedza chinhu chakachengetedzwa neyekunze mheni yekudzivirira system, kana iyo arcing daro inogona kuchengetedzwa. Mumamiriro ezvinhu aya, magetsi emheni haakwanise kupinda mudunhu reDC uye inongofungidzira kuwanda kunofungidzirwa (yekumanikidza ikozvino neparamende ye8 / 20 μs), uko mhando 2 yekudzivirira yekudzivirira chishandiso chakwana, semuenzaniso SLP40-PV nhevedzano, inogadzirwa yeiyo voltage ye600 V, 800 V, uye 1000 V, zvakare iine kana isina chiratidzo kure.

Kana tichijekesa zvigadzirwa zvekudzivirira, isu tinofanirwa kufunga nezve AC parutivi pamwe nedhata uye mitsara yekutaurirana, ayo anowanzo shandiswa mune yanhasi PV magetsi chiteshi. Chiteshi chePV chemagetsi chinotyisidzirwawo kubva kudivi reDC (kugovera) network. Padivi iri, kusarudzwa kweSPD yakakodzera kwakanyanya uye kunoenderana nechishandiso chakapihwa. Sevadziviriri vekudzivirira kwepasirese, tinokurudzira chishandiso chemazuva ano cheFLP25GR, icho chinobatanidza ese matatu 1 + 2 + 3 mhando mukati memamita mashanu kubva panzvimbo yekumisikidza. Inoratidzira mubatanidzwa wevaristors uye inosunga mheni. LSP inopa akati wandei akateedzana emidziyo yekudzivirira ekuyera uye masystem sisitimu pamwe nemitsara yekufambisa.
